ANITA was placed in Antarctica because there is little chance of interference from other signals. To capture the emission signals, the balloon-borne radio detector is sent to fly over stretches of ice, capturing what are called ice showers. Credit: Stephanie Wissel / Penn State

Recently, a group of scientists at the University of Pennsylvania, have detected mysterious radio signals, that seem to confound the very foundation of particle physics. As per their journal paper, the signals were discovered by the scientific instrument, Antarctic Impulsive Transient Antenna (ANITA).
